Inconspicuous mode for mobile devices

ABSTRACT

A communication device is configured to switch from a normal mode of operation to an inconspicuous mode of operation in which a reduced set of information is presented on a home screen of a display of the device in comparison to a set of information presented on the home screen in the normal mode of operation. In addition, other display properties such as contrast and brightness may be adjusted to make them less conspicuous. The home screen in the inconspicuous mode of operation is less obtrusive or conspicuous to individuals than in the normal mode of operation. The device may enter the inconspicuous mode upon user request or by detecting at least one environmental condition using a sensor available to the mobile communication device. The environmental condition may be anything that the device can detect or sense in its surrounding environment such as ambient light or sound. The device may return to the normal mode of operation by user request or when the environmental condition is no longer present.

BACKGROUND

Mobile communication devices are increasingly important and are incommon use in many environments. Accordingly, individuals often keepthem on their person throughout large portions of the day. In part, theubiquity of mobile communication devices arises because such devices areoften capable of performing many different functions. For instance,mobile communication devices may support any of a variety ofapplications, such as a telephone application, a video conferencingapplication, an e-mail application, an instant messaging application, ablogging application, a digital camera application, a digital videocamera application, a web browsing application, a digital music playerapplication, and/or a digital video player application, and so on.

One problem with the ubiquity of these devices in so many differentenvironments is that their use in not appropriate in all settings. Asone common example, in a theater the sound from a mobile communicationdevice and the light from its display can be distracting to othertheater patrons. Even if the user deactivates certain features such asaudio notification of incoming calls and text messages, users may stillrely on other features while in the theater. For example, mobilecommunication devices are sometimes used as a substitute for a watch,and these people may use the device to check the time while in thetheater. Even this use of the device can be distracting to other theaterpatrons because of the light emanating from the display when the userlooks at the display to see the time. Many of these same and othersimilar problems arise not only in theaters, but in other environmentsand venues such as in a meeting room, automobile and even bedrooms.

SUMMARY

In some implementations a communications device may be placed in aninconspicuous mode in which its display and certain hardware featuresare modified so that the device is better suited for an environment suchas a theater or other venue in which individuals other than the user donot wish to be disturbed by the communication device. While in theinconspicuous mode, specific features may be disabled such as thegeneration of sound. Additionally, the appearance of the display may bechanged. For instance, the brightness may be decreased, the contrast maybe increased, and information presented on the home or default screenwill be changed. For instance, all information and notifications may beremoved from the screen except for a limited number of items that may beuser-selectable. For instance, in one implementation, any backgroundimages may be replaced with a dark solid color and only a singlenotification (e.g., time-of-day) is presented which is easy to read onthe dark screen. In one particular implementation, the communicationdevice is configured to enter the inconspicuous mode upon user requestor upon detecting at least one environmental condition using a sensoravailable to the mobile communication device. The environmentalcondition may be anything that can be detected or sensed by the mobilecommunication device while in the venue or other environment. The sensordetermines if the detected environmental condition satisfies at leastone prescribed criterion. If it does, the communication device switchesfrom a normal mode of operation to an inconspicuous mode of operation inwhich a reduced set of information is presented on a home screen of adisplay of the mobile communication device in comparison to a set ofinformation presented on the home screen of the display of the mobilecommunication device in the normal mode of operation. The home screen inthe inconspicuous mode of operation is less obtrusive or conspicuous toindividuals than in the normal mode of operation.

As previously mentioned, an inconspicuous mode is a mode of operationthat can be activated on a communications device which modifies itsdisplay and certain hardware features so that the device is bettersuited for an environment such as a theater or other venue in whichindividuals other than the user do not wish to be disturbed by thecommunication device. While in the inconspicuous mode, specific featuresmay be disabled such as the generation of sound. Additionally, theappearance of the display will be changed. For instance, the brightnessmay be decreased, the contrast may be increased, and informationpresented on the home or default screen will be changed. For instance,all information and notifications may be removed from the screen exceptfor a limited number of items that may be user-selectable. Moreover, theitems remaining on the screen can by presented in a less disturbingmanner by, for instance, controlling the background, such as by makingit a solid color. In general, the user will be able to customize theitem or items that appear on the display when the device is in theinconspicuous mode.

FIG. 2 shows an example (a) of the default or home screen when themobile communication device is in its normal mode of operation, and anexample (b) of the default or home screen when the mobile communicationdevice is in its inconspicuous mode of operation. As shown in example(a), in its normal mode, the screen presents a background image andprovides various information concerning device status, the number ofunanswered voice and text messages and so on. On the other hand, asshown in example (b), the only information presented is the current timeof day and a small indicator, which serves as notification to the userthat some prioritized event has occurred. For example, the indicator mayindicate that a message has been received from one more individuals whohave been specified by the user as being of high priority. The indicatorwill not be displayed if messages have only been received from otherindividuals. Other than showing the time of day and the indicator, theremainder of the display will be dark in this implementation.

FIG. 3 shows one example of a system for implementing an inconspicuousmode in a mobile communication device such as the device shown inFIG. 1. The system includes a graphical, text-based or other userinterface 202 that is presented to a user, through which, among otherthings, the user can configure various settings for the inconspicuousmode. The user interface 202 interacts with the operating system 204.The operating system 204 interacts with an inconspicuous mode component206 for controlling access to various applications or features 208 ofthe device, including certain hardware features such as the display andother output devices such as the speaker. In some implementations theinconspicuous mode component 206 may be directly incorporated into theoperating system.

The user interface 202 allows a user to select which items are to appearon the display while the device is in the inconspicuous mode. It mayalso allow the user to control other aspects of the inconspicuous modesuch as the precise brightness level of the display when in theinconspicuous mode, the environmental conditions or factors that mayautomatically trigger the device to enter the inconspicuous mode(discussed in more detail below), and so on. Among other things, theuser interface 202 may provide a list or menu from which the user canselect or unselect those specific items that are to be displayed whilein the inconspicuous mode. The items or information which are presentedrepresent a limited subset of the items or information that would bepresented in the normal mode.

Generally, the behavior of any application or feature installed on thedevice can be modified while the device is in the inconspicuous mode. Insome implementations the user interface may present a default set ofitems whose appearance on the display will be modified, as well as thespecific way in which those items will be modified while the device isin the inconspicuous mode.

For example, the user may specify that only the time so day should bedisplayed in inconspicuous mode and that its brightness should bereduced by e.g., 60%, from its maximum value. The user may also be ableto choose how other aspects of the display are presented. For instance,the user may be given a choice of font sizes and colors from which tochoose. The choices presented to the user may be those which arerelatively inconspicuous in comparison to the choices that wouldotherwise be available.

The mobile communication device can enter the inconspicuous modeautomatically or upon user selection. Automatic entry can be triggeredupon the occurrence of any of a wide variety of events that can bedetected by the mobile communication device. Many of these eventsinvolve the detection of environmental conditions that can be detectedby one or more sensors incorporated in the mobile communication device.Two examples of such environmental conditions are ambient sound andambient light levels, which the device can detect using a light sensorand microphone, respectively.

In one example, the mobile communication device may enter theinconspicuous mode when it detects that the ambient light level hasfallen below a certain level, which may reflect, for instance, that theuser is in a darkened theater or is about to go to bed. Likewise, thedevice may enter the inconspicuous mode when it detects that the ambientsound or noise level has fallen below a certain level, which may againreflect, for instance, that the user is in a darkened theater in which amovie is about to begin, or that the user is about to go to bed.Moreover, these environmental conditions may be detected and used incombination to better assess whether the device should enter theinconspicuous mode. As one example, if the device detects both a lowlight level and a low noise level, the device may be configured (bydefault or user specification) to enter the inconspicuous mode, whereasif the device detects both a low light level and a noise level abovesome threshold, the device may be configured (by default or userspecification) so that it does not enter the inconspicuous mode. Theformer situation may indicate, for instance, that the device is locatedin a bedroom in which the user is sleeping, while the latter situationmay indicate, for instance, that the user is watching TV or listening tomusic in a darkened room.

Many additional conditions reflecting the environment in which themobile communication device is located may be used to determine when toenter (and possibly exit) the inconspicuous mode. For instance, in oneimplementation the mobile communication device includes a devicelocation module such as a global positioning system (GPS) receiver(e.g., GPS module 135 shown in FIG. 1). GPS receivers are capable ofupdating a device's location on a real or near real-time basis. Thelocation is typically represented in terms of the physical coordinatesof the mobile device on the surface of the Earth, which typicallyoutputs a location as latitude and longitude values. The GPS receivercan also employ other geo-positioning mechanisms, including, but notlimited to, triangulation, assisted GPS (AGPS), E-OTD, CI, SAI, ETA, BSSor the like, to further determine the physical location of the mobilecommunication device 200. If the mobile communication device can compareits location data to a map or other database that identifies the venuescorresponding to that location, the device can determine whether andwhen it should enter the inconspicuous mode. If, for instance, thedevice uses its location information to determine that it is in atheater, it may automatically enter inconspicuous mode. The venue map ordatabase information needed to identify the venue in which the device islocated, along with the processing necessary to compare the locationdata to the venue map or database information may be resident on themobile communication device or it may be in whole or in part offered tothe mobile communication device as a cloud-based service.

Yet another source of data that the mobile communication device may useto determine when it is in a venue that should trigger initiation of theinconspicuous mode is calendar data that may be available from ascheduling application resident on the device. For instance, if the userenters into the device's calendar that he or she will be attending thetheater on Tuesday at 7 pm or that attending a dinner on Thursday at 8pm, the inconspicuous mode component 206 may access this data andperform a keyword search to determine those days and times when itshould enter the inconspicuous mode. Such a calendar or schedulingapplication may be embodied, for example, in commercially availablesoftware such as Microsoft Corporation's Outlook® messaging andcollaboration client.

Other applications resident on the device may be used to obtaininformation for determining when to enter the inconspicuous mode. Forexample, if the device is used to purchase tickets or the like throughits web browser or through an application that employs a Near FieldCommunication (NFC) or RFID sensor, which allows the user to swipe thedevice over an NFC or RFID tag to purchase or claim a ticket, theincoming information can be parsed by the inconspicuous mode component206 to determine where and when to enter the inconspicuous mode.

In other implementations mobile communication device may, through othercomponents, obtain other information that might be employed to determinethe location of the device, including for example, Wi-Fi access pointshaving particular service set identifiers (SSIDs), e.g., “home,” “ABCtheater”, or even a MAC address, IP address, or the like which isassociated with a specific location. In some cases the venue itself mayparticipate in the venue determination process. For example, at thebeginning of a movie, the theater may send a localized broadcast to alldevices within the venue instructing them to enter an inconspicuousmode. The broadcast may be of any type that can be detected by themobile communication device and may be, for example, in the form of anaudio, optical, RFID or text message.

FIG. 4 is a block diagram depicting in more detail one particularimplementation of the inconspicuous mode component 206 shown in FIG. 3.As shown, the inconspicuous mode component includes, among other things,an inconspicuous mode process 315, inconspicuous state API 330, usersettings 340, display control processes 350 and other devices processes360.

In operation, information obtained from one or more environmentalsampling sensors 320 (e.g., microphone, light sensor, GPS) or one ormore applications 310 (e.g., calendar, web browser) initiates aninconspicuous mode process 315 that communicates with the deviceoperating system via an inconspicuous state API 330. The inconspicuousmode process 315 extracts or otherwise parses pertinent information fromthe sampling sensor(s) 320 and/or the application(s) 310. Theinconspicuous mode process 315 also accesses user settings 340 that aremaintained in memory or other storage via inconspicuous state API 330.The user settings 340 contain a record of information provided by theuser through the user interface 202 (see FIG. 3). The informationspecifies the conditions under which the device should enter theinconspicuous mode and the actions that the device should take while inthe inconspicuous mode. If no user settings have been specified, then adefault record may be accessed by the inconspicuous mode process 315.The inconspicuous mode process 315 compares the pertinent informationextracted or parsed from the sampling sensor(s) 320 and/orapplication(s) 310, and compares it to the information obtained fromuser settings 340 or from default settings. If the protected modeprocess 315 determines that the environmental conditions indicate thatthe device should enter the inconspicuous mode, it causes the protectedstate API 330 to perform any adjustments to the information presented onthe device display as well as any adjustments to device hardware (e.g.,speaker or ringer) that are needed to place the device in theinconspicuous mode.

FIG. 5 is a flowchart illustrating one example of the operation of amobile communication device having the inconspicuous mode systemdescribed herein. The method begins at step 510 when at least oneenvironmental condition is detected in a venue where the mobilecommunication device is located using a sensor available to the mobilecommunication device. The environmental condition may be anything thatcan be detected or sensed by the mobile communication device while inthe venue. Illustrative conditions include light or sound levels andlocation information. At decision step 520, the sensor determines if thedetected environmental condition satisfies at least one prescribedcriterion. If not, then at step 530 the process returns to step 510where the environmental condition continues to be monitored. If thedetected environmental condition satisfies the environmental condition,the communication device switches from a normal mode of operation to aninconspicuous mode of operation in which a reduced set of information ispresented on a home screen of a display of the mobile communicationdevice in comparison to a set of information presented on the homescreen of the display of the mobile communication device in the normalmode of operation. The home screen in the inconspicuous mode ofoperation is less obtrusive or conspicuous to individuals than in thenormal mode of operation.

FIG. 6 is a flowchart illustrating another example of the operation of amobile communication device having the inconspicuous mode systemdescribed herein. The method begins in step 610 by extractinginformation from an application residing on the mobile communicationdevice indicating that the mobile communication device should enter theinconspicuous mode at a specified time on a specified date. At thespecified time on the specified date, the mobile communication switchesin step 620 from the normal mode of operation to the inconspicuous modeof operation. In one implementation, in the inconspicuous mode allinformation that otherwise would be presented on the home screen of themobile communication device in the normal mode of operation iseliminated except for time of day information and possibly an indicatorof prioritized information.

The mobile communication device can exit the inconspicuous mode andreturn to the normal mode upon the user's request. For instance, in someimplementations the user may swipe an appropriate portion of the screenor shake the device in order to return to normal mode. The device mayalso return to the normal mode of operation when the environmentalcondition which caused it to enter the inconspicuous mode is no longerpresent.

As used in this application, the terms “component,” “module,” “engine,”“system,” “apparatus,” “interface,” or the like are generally intendedto refer to a computer-related entity, either hardware, a combination ofhardware and software, software, or software in execution. For example,a component may be, but is not limited to being, a process running on aprocessor, a processor, an object, an executable, a thread of execution,a program, and/or a computer. By way of illustration, both anapplication running on a controller and the controller can be acomponent.
